Expression of DLX3 in chick embryos

Higher vertebrates appear to possess six genes encoding a homeodomain of the distal-less type. We report the cloning and expression pattern of the chicken DLX3 gene, a homeobox gene highly related to the DLX5 gene with regard to both the encoded protein structure and the expression pattern. DLX3 RNA was observed during the development of the olfactory and otic placodes, in the distal portion of th

Ectodermal patterning in the avian embryo: epidermis versus neural plate

Ectodermal patterning of the chick embryo begins in the uterus and continues during gastrulation, when cells with a neural fate become restricted to the neural plate around the primitive streak, and cells fated to become the epidermis to the periphery. The prospective epidermis at early stages is characterized by the expression of the homeobox gene DLX5, which remains an epidermal marker during ga

Photo-stability of CsPbBr3 perovskite quantum dots for optoelectronic application

Due to their superior photoluminescence (PL) quantum yield (QY) and tunable optical band gap, all-inorganic CsPbBr3 perovskite quantum dots (QDs) have attracted intensive attention for the application in solar cells, light emitting diodes (LED), photo detectors and laser devices. In this scenario, the stability of such materials becomes a critical factor. We hereby investigated the long-term stabi

Patterning of the chick forebrain anlage by the prechordal plate

We analysed the role of the prechordal plate in forebrain development of chick embryos in vivo. After transplantation to uncommitted ectoderm a prechordal plate induces an ectopic, dorsoventrally patterned, forebrain-like vesicle. Grafting laterally under the anterior neural plate causes ventralization of the lateral side of the forebrain, as indicated by a second expression domain of the homeobox

Digital strategies for two-sided markets : A case study of shopping malls

Digitalization is fundamentally changing the retailing ecosystem for shopping malls as digital and analogue elements get increasingly intertwined. We conceptualize shopping malls as two-sided markets whose primary function is connecting shoppers and retailers. By means of an interpretative case study, the article then presents an omnichannel strategy typology for how shopping malls can meet the ev

Prediction models of free-field vibrations from railway traffic

Many cities experience an increasing population leading to a need for urban densification. In these cities, unused land close to railways will have to be developed with new residential and office buildings. The infrastructural demand will also increase, resulting in heavily trafficked roads and railways close to w here people work and live. Annoyance from traffic-induced vibrations and noise is ex
